功能介绍

自定义筛选条件,批量删除人脸库中的符合指定条件的多张人脸。

前提条件:

application/json请求的body中,请使用标准Json格式。

URI

DELETE /v1/{project_id}/face-sets/{face_set_name}/faces/batch

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方法请参见获取项目ID/账号名/AK/SK

face_set_name

String

人脸库名称。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

Token认证就是在调用API的时候将Token加到请求消息头,从而通过身份认证,获得操作API的权限,响应消息头中X-Subject-Token的值即为Token。

表3 请求Body参数

参数名

参数类型

是否必选

说明

filter

String

过滤条件,具体参见filter语法

响应参数

状态码:200

表4 响应Body参数

参数名

参数类型

说明

face_set_name

String

人脸库名称。

调用失败时无此字段。

face_set_id

String

人脸库ID。

调用失败时无此字段。

face_number

Integer

删除的人脸数量。

调用失败时无此字段。

error_code

String

调用失败时的错误码,具体请参考错误码

调用成功时无此字段。

error_msg

String

调用失败时的错误信息。

调用成功时无此字段。

请求示例

X-Auth-Token值获取方法请参见认证鉴权

  • 请求样例(使用filter删除)
    DELETE https://{endpoint}/v1/{project_id}/face-sets/showFaceSet/faces/batch
    Request Header:
    Content-Type: application/json
    X-Auth-Token: MIINRwYJKoZIhvcNAQcCoIINODCCDTQCAQExDT...
    
    Request Body:
    {
      "filter" : "age:[20 TO 30]"
    }
  • Python3语言请求代码示例(其他语言参照下列示例编写或使用FRS SDK)
    # -*- coding:utf-8 -*-
    
    import requests
    import base64
    
    endpoint = '开通服务所在region的人脸识别服务域名'
    project_id = '开通服务所在region的用户项目ID'
    token = '用户获取得到的实际token值'
    headers = {'Content-Type': 'application/json', 'X-Auth-Token': token}
    
    face_set_name = 'showFaceSet'
    url = "https://{endpoint}/v1/{project_id}/face-sets/{face_set_name}/faces/batch".format(
        endpoint=endpoint, project_id=project_id, face_set_name=face_set_name)
    body = {"filter" : "age:[20 TO 30]"}
    response = requests.delete(url, headers=headers, json=body, verify=False)
    print(response.text)
